HERB, DIE BUFFALO,NEW YGRK, ASSIGNOR TU IVif-LNUFACTURING 00., INCL, OF BUFFALO, NEWYQfl-K, A GORPORFJIIUN OF NEW YORK HOLDER FOR SPINNER RINGS Applicationfiled September 5, 1928.

This invention relates to improvements in the holders or mountingsemployed in connection with the spinner rings of spinning machines.

As now constructed, these spinning ring holders consist of a base memberhaving upr1ght brackets rising therefrom which are oifset laterally at apoint below their upper ends to provide seats or ledges upon which thespinner ring is adapted to seat, and be yieldingly held in place, thebrackets being strained or flexed sidewise to effect the application andremoval of the ring to and from the holder. This construction not onlynecessitates an extreme effort on the part of the attendant to apply andremove the spinner rings, but it is an awkward operation as well,especially on the lower frames of the spinning machine; furthermore, theside strains on the holder-brackets resulting from the effort requiredto insert and remove the rings causes the base of the holder to bend orwarp out of shape, thereby throwing the ring out of true and producingan uneven bearing for the bar traveler which revolves thereon.

The chief objects of my invention are to provide a holder of thischaracter which has been designed to permit the ready application andremoval of the spinner ring conveniently and with a minimum of effort,and which is self-centering and provides a positive, true bearing forthe traveler at all times.

A further object of the invention is to so construct the holder that thering is forced into gripping position by a direct downward movement.

A still further object is to provide the holder with stops separate fromthe ringgripping elements thereof which serve to limit and gage thecorrect operative position of the ring in the holder.

In the accompanying drawings Figure 1 is a top plan view of my improvedholder showing the spinner ring in position thereon. Figure 2 is anenlarged transverse section taken on line 2-2, Figure 1. Figure 3 is anenlarged fragmentary transverse section taken in the plane of line 2-42,Figure 1 and showing the spinner ring about to be forced downwardlybetween the clamping Serial No. 304,081.

posts or brackets. Figure 4 is a top plan view of the holder with thespinner ring removed.

Similar characters of reference indicate corresponding parts throughoutthe several views.

In spinning machines of the character to which my invention isparticularly applicable, the threads to be twisted are delivered by feedrolls (not shown) to a take-up spool 10 and traversing the same is avertically reciprocating bar 11, the spool extending through an opening12 in the bar.

Mounted on the reciprocating bar 11 and surrounding the take-up spool isthe sup porting member or holder for the spinner or traverse ring 13upon which the customary bar traveler 142 is adapted to revolve. Duringthe operation of the machine, the bar traveler assumes a substantiallyupright position and revolves with and about the take-up spool, thethread passing under the traveler before being wound upon the spool andthe traverse bar being reoiprocated so that the threads are uniformlywound upon the spool in layers.

The improved holder is preferably stamped or otherwise formed from sheetmetal and consists of an annular attaching base 15 from the outer edgeof which projects a pair of oppositely facing slotted cars 16 forsecurely fastening the holder to the bar 11 in any approved manner.Rising from the inner edge of the attaching base is a neck 17 which isspaced from the opposing inner edge of the spinner ring 13 to provide anannular channel 18 for receiving the depending legs of the bar traveler,the underside of said ring forming a bearing face for the legs of thetraveler.

The spinner ring 13 is detachably mounted within the holder and isadapted to be sprung into place therein by a direct downward thrust. Forthis purpose a plurality of expansible or yielclable brackets or posts19, three being shown in the drawings, project upwardly in asubstantially vertical position, although it is desirable that thesebrackets normally deflect inwardly at a slight angle to the vertical toinsure a positive grip on the sides of the spinner ring. The upper endssaid base. The purpose of this construction is to bring the brackets outof the path of movement of the, traveler-legs. Y v

Means are provided separate and independent from the brackets 19 forsupporting the spinner ring firmly in the holder and forpredeterminingthe positioning of the same in its proper spaced relationabove the holder-base 15. These means are positioned radially betweenthe brackets or at the highest points of fleXure to which the base issubjected when the spinner ring is engaged with said brackets, andpreferably consist of upwardly facing stop-lugs or flanges 22 formedintegral with the base and located at substan tially the same radialdistance from the center of the holder as are the brackets 19. As shownin Figure 2, the outer lower edge of the spinner ring is adapted to reston the top edges of the lugs 22 and the latter are of a uniform heightto insure a true and even bearing for the ring and to maintain it in therequired spaced relation to the base of the holder. By arranging thestop-lugs or sea s forthe spinner ring in this manner, a true andpositive three-point bearing is provided for the spinner ring and thetendency of the base of the holder to warp or bend out of shape iscounteracted by these stop-lugs, which positively maintain the ring inuniform spaced relation to the holder and afford a free movement of thebar traveler at all times. V

This improved holder is manifestly simple and inexpensive inconstruction; itenables the spinner ring to be applied to it with aminimum of effort; and it insures a selfcentering of the ring relativeto the'holder and affords a true andeven bearing for the bar traveler atall times.

I claim as my invention A device of the character described, comprisingan annular base, circumferentiallyspaced, outwardly expansible bracketsrising from the outer edge thereof, the upper ends of said bracketsbeing flared outwardly, stop-lugs rising from the outer edge of saidbase and disposed between and terminating below the upper ends of thebrackets, and a detachable guide ring for a bar traveler adapted to befitted to said base by a direct downward thrust, the circumferencedescribed by the flared upper ends of the brack HENRY C.
